FILLING-REPLENISHING LOONI.

Specification of Letters Patent.

To (rl/ [I'll (JIM it may concern.-

Be it known that I, EDWARD S. STIMPSON, a citizen of the United States,and a resident of Hopedale, county of WVorcester, State ofMassachusetts, have invented an Improvement in Automatic Filling-Replenishing Looms, of which the following description, in connectionwith the accompanying drawings, is a specification, like characters onthe drawings representing like parts.

This invention relates to looms of the Northrop type, wherein therunning shuttle is provided automatically with a fresh supply of fillingfrom a reserve contained in a filling-feeder, such a loom forming thesubject-matter of United States Patent No. 529,9l0. Thefilling-carriers, either bobbins or cop-skewers, are supported at theirheads and tips in a rotatable fillingfeeder, which is moved whennecessary to present singly the filling-carriers into position to betransferred to the shuttle. From the several filling-carriers thefilling ends are led over the outer end of the feeder to an endholdermounted on the feeder in a manner familiar to those skilled in the artand in order to operate properly the filling end of the transferredfilling-carrier should be somewhat slackened to obviate any tendency tobreak as the replen ished shuttle is picked from the replenishingshuttle-box. WVhen running at speed, the vibration of the loom so shakesthe feeder that at times there is in a tendency of the fillingcarriersto rotate axially to thereby unduly tighten the filling ends or toslacken the same so much that before or during transfer the slack endwill be caught and broken.

My present invention relates more particularly to the construction ofthe filling-feeder of an automatic loom of the type referred to; and ithas for its object the production of means to prevent any axial rotationof the filling-carriers while supported in the fillingfeeder, butwithout exerting any positive locking action and requiring no additionalcare in manually placing the filling-carriers therein nor interferingwith their automatic transfer to the shuttle.

The novel features of my invention will be fully described in thesubjoined specification and particularly pointed out in the followingclaims. i

Figure 1 is a front elevation and partial section of thefilling-replenishing mechanism of a loom of the Northrop type referredto with one embodiment of my invention applied thereto. Fig. 2 is anouter side elevation of a portion of the inner end plate of the feederwhich supports the heads of the fillingcarriers. Fig. 3 is an enlargedperspective view of the head end of a filling-carrier, shown as acop-skewer, constructed in accordance with my invention. Fig. 4 is anenlarged cross-section through one of the holdingpockets of the feederon the line 4 i, Fig. 2; and Fig. 5 is a detail showing the lowerportion of the inner end plate of the feeder and the adjacent parts.

The stand A fixedly mounted on the breast-beam of the loom and having acircular flange 0, the horizontal stud a, on which is rotatably mountedthe hub a of the inner end plate (L of the fillingfeeder, provided withperipheral pockets 2 to receive the heads of the filling-carriers, theend-holding disk b and stud Fig. 1, rotatable with the feeder, thetransferrer f, and the outer end plate a, having its hub 14 connectedwith the hub a, may be and are all substantially as in United StatesPatent No. 755,252, granted to me on the 22d day of March, 190%.

The circular connected plates a a. rotate together in unison and supporta circularlyarranged series of filling-carriers, (herein shown ascop-skewers,) the heads 3 having their outer ends radially recessed, asshown in Fig. 3, by two intersecting and shallow dia metrical grooves 4.The plate a is provided with spring-controlled tip-holders 5, locatedopposite the pockets 2 to receive and sup port the tips 6 of thecopske\\'ers, as shown in Fig. 1, the tip-holders being substantially asshown in said Patent No. 755,252 and forming no part of my presentinvention. Intermittent rotation of the feeder is effected by well-knownmeans to bring one after another of the filling-carriers into positionto be transferred.

The back wall of each of the pockets 2 in the feeder-plate c is hereinshown as provided with a slight rib or lug 7, lying radially withrelation to the center of rotation of the plate,

Fig. 2, and transversely convex, as best.

shown in Fig. 4. Each lug is of such convexity and size as to readilyenter one of the shallow recesses 4 1n the end of the copskewer, thetip-holder spring 8, Fig. 1, acting through the tip-holder to press thehead of the cop-skewer against the back of the opposite pocket. When thelug enters one of the recesses 4, it will be manifest that the skewerwill be held frictionally from axial rotation, and hence the filling endcannot be either wound up or unwound, thereby obviating the objectionreferred to hereinbefore. As the lugs are radially located on the platea, they offer, no opposition to the removal of the skewer from thefeeder by the transferrer when transfer is called for. The recesses 4are shallow, and when the operative loads the feeder the skewers areplaced therein without regard to the cooperation of lug and recess, forif they do cooperate at once well and good; but if not the vibration ofthe feeder will soon effect such cooperation, and at the outside onlyoneuarter of a revolution of the skewer can t ke place before the lug 7enters a recess and stops further rotation.

This invention is particularly adapted for cop-skewers, as their solidheads can be readily recessed without any resulting weakness, and thelugs in the pockets are formed as a part of the feeder-plate when thelatter is cast.

Any suitable tip-holding device may be used instead of the form hereinshown, as the particular construction thereof has no bearing on myinvention.

The filling-carrier next to be removed from the feeder rests upon theusual support and guide 20, Fig. 5, and ordinarily the vibratory motionof the feeder on its axis causes the head of the filling-carrier to rubback and forth on the support, tending to rotate axially thefilling-carrier next to be removed. It will be manifest that thistendency is resisted by the invention herein set forth, but in anon-positive manner, as the rotative movement of a filling-carrier islimited to onequarter of a turn at the most.

Having fully described my invention,what

I claim as new, and desire to secure by Let ters Patent, is-

1. A filling-feeder for looms, comprising two connected plates adaptedrespectively to engage and support the heads and tips of a series offilling-carriers, the outer end of the head of each filling-carrierhaving one or more shallow radial recesses therein, and

means on the head-supporting plate of the feeder to frictionally andnon-positively co- .operate with a recess in each filling-carrier andprevent axial rotation of they same.

2. A filling-feeder for looms, comprising two connected plates adaptedrespectively to support the heads and tips of a series offilling-carriers, the outer end of the head of each filling-carrierhaving one or more shallow recesses therein, and lugs on thehead-supporting plate of the feeder to frictionally engage such recessedends of the filling-carriers and non-positively prevent axial rotationthereof.

3. A filling-feeder for looms, comprising two connected, rotatableplates, means on one plate to support the tips of a circularlyarrangedseries of filling-carriers each having a shallow radial recess in theouter end of its head, peripheral pockets on the other plate to receivethe heads of the fillingcarriers, and a lug in each pocket tofrictionally and nonpositively cooperate with the recessed end of theadjacent filling-carrier and prevent axial rotation thereof.

4. A filling-feeder for looms, comprising two connected, rotatableplates adapted respectively to engage and support the heads and tips ofa circularly-arranged series of filling-carriers, the outer end of thehead of each filling-carrier having two diametral, intersecting shallowrecesses therein, the headsupporting plate of the feeder havingperipheral pockets to receive the filling-carriers, and a radial lug onthe back of each pocket to cooperate with a recess in the head of thefilling-carrier therein the frictional engagement of the lug and arecess acting to prevent axial rotation thereof.

5. In a filling-feeder for looms, means to support the heads of aplurality of filling-carriers each having a shallow diametral recess inthe outer end of its head, and lugs on the supporting means tofrictionally cooperate with the recessed ends of the filling-carriersand prevent axial rotation thereof when the lugs and recesses register.

In testimony whereof I have signed my name to this specification inthepresence of two subscribing witnesses.
